Technical Field

[0001] The present application belongs to the technical field of sizing roller testing, and specifically relates to a sizing roller wear resistance testing device. Background Art

[0002] The shaping roller is an important processing equipment used to give materials specific shapes and sizes. It is widely used in the processing of materials such as plastics, rubber, and textiles. During the production process, since the shaping roller needs to be in contact with the material and apply pressure for a long time, if the wear resistance is insufficient, it will cause damage to the roller surface, affect the material forming effect, and even increase downtime for maintenance and reduce production efficiency. Therefore, wear resistance is one of its important performance indicators. In order to ensure that the wear resistance of the shaping roller meets the requirements, wear resistance testing becomes an indispensable part before production.

For example, the installation process is complicated and time-consuming, which affects the efficiency of the test. In addition, it is difficult to accurately simulate the friction and wear conditions in actual production during the test process, resulting in deviations between the test results and actual usage conditions. This not only affects the evaluation of product quality, but may also mislead the adjustment and optimization of subsequent production processes. For this purpose, a sizing roller wear resistance testing device is provided. Utility Model Content

The entire testing process is carried out in a constant temperature room, which helps to ensure the accuracy and reliability of the test results. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] refer to Figure 1 、 Figure 2 The middle part of the bearing seat 10 is fixedly installed with a rotating shaft 12, and one end of the rotating shaft 12 is fixedly installed with a fixing cylinder 13. The left and right ends of the shaping roller 8 are respectively inserted into the interior of the fixing cylinder 13, and the outer surface of the fixing cylinder 13 is threadedly connected with a locking bolt 14.

At this time, the personnel can tighten the four locking bolts 14, which makes it easy to limit and fix the left and right ends of the shaping roller 8, so that the subsequent rotating shaft 12 and the fixing cylinder 13 can drive the shaping roller 8 to rotate.

[0029] refer to Figure 1 、 Figure 2 A pulley 15 is fixedly installed on the outer surface of one end of the right rotating shaft 12, and a driving rotating mechanism 16 connected to the pulley 15 is provided on one side of the right fixed plate 9; through the provided driving rotating mechanism 16, it is easy to drive the pulley 15, the rotating shaft 12, the fixed cylinder 13 and the shaping roller 8 to rotate, which facilitates the wear resistance test of the shaping roller 8.

[0030] refer to Figure 1 、 Figure 2 The driving rotation mechanism 16 includes a servo motor 25 and a second pulley 26. The servo motor 25 is fixedly installed on one side of the right fixed plate 9. The driving end of the servo motor 25 is fixedly installed with a second pulley 26. The outer surface of the second pulley 26 is provided with a transmission belt. The second pulley 26 is connected to the first pulley 15 through the pulley; the servo motor 25 drives the second pulley 26 to rotate. At this time, the second pulley 26 drives the transmission belt and the pulley 15 to rotate, so that the shaping roller 8 can rotate.

[0031] refer to Figure 1 、 Figure 2 , a speed sensor 17 is fixedly installed on one side of the right fixed plate 9; through the set speed sensor 17, it can accurately monitor the speed of the shaping roller 8 to ensure the accuracy and reliability of the test. The control box installed on one side of the mounting seat 1 is the control center of the system, which contains control elements. These elements are electrically connected to the speed sensor 17 and the pressure sensor 7. At the same time, the pressure sensor 7 is also working to monitor the pressure between the wear-resistant test seat 5 and the shaping roller 8. When monitoring the pressure between the wear-resistant test seat 5 and the shaping roller 8, the pressure sensor 7 can apply the force control box to the wear-resistant test seat 5 in advance by the limit rod 6. After these data are processed by the control element, they can be displayed in real time on the display screen connected to it, which is convenient for testers to monitor the test process and understand the wear status of the shaping roller 8. The control box and the control elements inside it are all existing structures. This application only uses them without improving their structure, so I will not go into too much detail here.

[0032] The implementation principle of the embodiment of the sizing roller wear resistance testing device of the present application is as follows: when performing a wear resistance test on the sizing roller 8, the operator first installs the device in a constant temperature chamber to ensure a stable test environment. Next, the operator activates the electric cylinder 3, which drives the mounting plate 4 and the wear resistance test seat 5 upward through its telescopic function, thereby facilitating adjustment of the height of the sizing roller 8 so that it corresponds to the fixed cylinder 13. The universal motor 24 drives the bidirectional screw rod 23 to rotate, thereby causing the slider 19 and the connecting plate 21 to drive the two fixed plates 9 to move in directions relative to each other. This action facilitates the insertion of the two ends of the sizing roller 8 into the interior of the fixed cylinder 13.

[0033] Then, the servo motor 25 drives the rotating shaft 12, the fixed cylinder 13 and the shaping roller 8 to rotate together through the transmission of the pulley 2 26, the transmission belt and the pulley 1 15. At this time, the personnel can start the electric cylinder 3 again, and the electric cylinder 3 pushes the mounting plate 4 to continue to move upward. At this time, the pressure value generated by the contact between the pressure sensor 7 and the bottom of the wear-resistant test seat 5 increases. This pressure value is transmitted to the control box on the side of the mounting seat 1 in real time through the sensor and displayed on the display screen. When the pressure sensor 7 reaches a certain pressure value, the personnel stops the electric cylinder 3. At this time, the wear-resistant test seat 5 contacts the shaping roller 8 and performs a wear resistance test under the continuous rotation of the shaping roller 8. Due to the long-term contact Due to the friction, wear will occur between the shaping roller 8 and the wear-resistant test seat 5. This wear causes the pressure value monitored by the pressure sensor 7 to change. The components inside the control box are combined with the data of the pressure sensor 7 and the speed sensor 17 to calculate the wear amount of the shaping roller 8. The electric cylinder 3, mounting plate 4 and wear-resistant test seat 5 of the device can not only be used for the wear resistance test of the shaping roller 8, but also assist in its installation and disassembly, making the operation more convenient. In addition, through the cooperation of the pressure sensor 7 and the speed sensor 17, the wear amount of the shaping roller 8 can be calculated more accurately, and the accuracy of the test is improved. The entire testing process is carried out in a constant temperature room, which helps to ensure the accuracy and reliability of the test results.
